Abstract
Accurate deception detection is a desirable goal with many applications including credibility assessment, security screening, counter-terrorism, and homeland security. However, many deception detection methodologies involve intrusive sensors or other limitations that preclude their use in a covert manner. Posturography may overcome these limitations by using minimally invasive force platform technology. In this study, we tested the hypothesis that posturography would reveal deception-related increases in postural rigidity similar to those observed with previous methodologies. Participants were randomly assigned to a control (CG) or experimental group (EG), and interviewed about the contents of a backpack in their possession while standing on a force platform. EG participants were asked to conceal the presence of several "prohibited" items in the backpack from the interviewer. Center of pressure (COP) measures from the force platform were used to characterize postural sway during participants' verbal responses. We observed a significant deception-related increase in sway frequency, an effect primarily occurring during longer responses that is likely related to increased cognitive load. These findings suggest deception-related increases in postural rigidity as reported in previous work, and demonstrate the feasibility of using posturography as a deception detection tool.
